MEDIUM AND LARGE ROTARY SCREW RANGE
(GA 30+ - 90 SERIES)

GA 30+ - 90 Oil-injected Rotary Screw
Compressor series
Assured Reliability
The GA is designed,
manufactured and tested in accordance with ISO 9001, ISO 14001 and ISO 1217,
Ed. 3, Annex C. The latest generation of Atlas Copco’s unique patented oil-injected
screw element, powered by a maintenance-free drive system, ensures a long and
trouble free life at the lowest operating cost. Engineered to provide
reliability even in ambient temperatures up to 55°C/131°F, the GA takes
reliability to a new level.
Air System Integration
The GA brings the
compressed air system to where you need it: the point of use. Its low noise
operation and integrated air treatment equipment eliminate the need for a
separate compressor room – reducing piping costs and internal system pressure
drop. GA compressors are delivered ready for use, reducing installation costs
to a minimum.
Built to last
Maintenance Free Drive System
The GA drive system is
100% maintenance free – eliminating the risks inherent to the
greasing of conventional motor bearings. Patented technology
allows the drive system to run in ambient temperatures up to
55°C/131°F.*
Oil Filter
A high efficiency oil
filter removes 300% smaller particles than a conventional
filter, providing clean oil to extend the lifetime of all lubricated
parts in the compressor. The oil filter rating of
ß12=75 sets a new industrial compressor standard that is fully
compliant with ISO 16889.
Aftercooler With Integrated Water Separator
The GA’s aftercooler
with integrated water separator immediately removes 100%
of condensate – avoiding the risk of corrosion in
downstream equipment and improving air quality compared to
conventional cyclone separators.
Electronic Water Drains
The GA’s no loss drains
eliminate the waste of compressed air that conventional
drains create. The drains communicate
with the compressor controller to ensure the constant
removal of condensate. A large diameter drain
port reduces the potential for clogging, providing
trouble free operation.
Electrical Cubicle Cooling Booster
The main cooling fan
cools the electrical cubicle, ensuring operating temperatures are
strictly regulated even in ambient temperatures up to
55°C/131°F.*
* Standard up to
46°C/114.8°F, optional high ambient version up to 55°C/131°F.
Oil Separator
Innovative filter
material removes oil particles from the compressed air while
minimizing pressure drop. This results in optimal
air quality at the highest efficiency.
Inlet Valve
The inlet valve is sized
for maximum flow to eliminate any inefficient pressure
drops. The valve is operated
through vacuum and air pressure to offer superior
reliability compared to spring operated inlet valves.
Inlet Filter
A heavy duty air intake
filter protects the compressor components by removing
99.9% of dirt particles down to 3 microns.
The Latest Element Technology
Atlas Copco is committed
to developing the most efficient screw element for each GA
generation. Developed from extensive R&D by dedicated Atlas Copco
engineers, the latest version of the patented oil-injected
rotary screw element provides unrivalled efficiency and
reliability. |
